Will this saw work as a tree pruner when a clipper pruner is not strong enough ??

Asked by DBW January 29, 2013

Answers

This is all I have used the saw for. I used the diablo pruning blade. I have cut down trees with this saw that are over 8 inches thick. Multiple battery uses of course but works great on branches especially less than 4 inches.

Not clear if this comes w 1 battery or 2; it says 1 in one place 2 in another

It comes with 2 batteries.

Does this drill have a light option?

Asked by augs November 18, 2013
10
Answers

I has a light, it is not an option it is included, flush with body under the chuck. It also has a soft off in which it slowly dims after trigger is released AND it will come on with a light trigger press to light things up before you start drilling/driving.

Does the recharger come with this item?

1 or 2 batteries?

Answers

Not sure what your question is. The saw comes with 1 (one) battery. I would recommend buying an extra battery and having it charged before your start a job.

I use this all the time with the larger m12 batteries. No issues unless you're in a REALLY tight space.

Customer review from milwaukeetool.com logo
Bought this needing to cut holes in plywood for work. The 1.5 mah battery lasted for five cuts barely. Even with the 4 mah it barely lasted 20 cuts. I’m not pleased with this. I have the m12 fuel hammer drill and impact combo and love then. Even have the m12 3/8 impact for the shop and it works amazing, sadly I’m not pleased with this hacksaw. Doesn’t last long and is slow

This tool is light weight so my wife can use it to. The batteries are small enough to carry an extra in a pocket or tool belt and buttery life is far greater than expected. Plenty of power but if you are cutting 2 x 4 or nails the battery life is reduced. If you are doing this a lot you may want a corded saw but I love this tool.

I've had this tool about a year now and I really like it's cutting ability & small size. This little hackzall is really quite the beast, you put on the right blade for the job and it'll work just like it's big brother for many jobs! I now go to it first and I'm always amazed how well it cuts! I only wish they would put the slide lock/unlock switch somewhere else, maybe even just a little higher, as it gets hit by accident all the time by my hand and I have to stop what I'm doing to push it back to unlock, the same issue goes for their drill & drivers too for that matter. I've use this tool with attachments as well like scraping blades & metal brushes for paint prep (see pic) and it does a good job with those attachments too. I've even thrown on a tree limb cutting blade to trim my trees & bushes, it's so much, easier, faster, cleaner & safer than a chain saw. If you found this review helpful please click on the thumbs up. Thanks!

The Milwaukee 12-Volt Lithium-Ion Cordless 3/8-inche Drill/Driver Kit with two 1.5 Ah Batteries, Charger, & Tool-Bag is a top-value at an affordable price. You pay a little more than for the off-brands, but this top-notch drill/driver kit is worth more than the price Milwaukee Tool charges you for it. It's a bargain. Invest in the future. Buy this set. It works great for metal-work and wood, etc.

I'm Just diy-er who loves quality tools. I used it and bought it cause I had to get into a confined space. To cut some drainpipe. It did the job. Took too long. I should of got a corded saw or a m18 for my application. I just bought the wrong tool... I believe this to be a good tool. It was my fault for using something not designed for the job.
